Plate-fin heat exchangers – Design variants
Linde Engineering’s plate-fin heat exchangers (PFHEs) come in a number of different design variants, providing the perfect solution for a wide range of requirements.

Plate-fin heat exchangers play a key role in many different industries. We offer a range of different designs for various cryogenic applications.

Single blocks

A single PFHE- blocks comprises the Brazed core, Stub ends and Flanges.

Benefits:

Very compact design

Low weight

Small possible temperature differences

Highly efficient heat transfer

Low pressure drops

Piped PFHE systems

A piped PFHE system comprises several exchanger blocks that are assembled and installed in a transport frame with support beams. Each battery of blocks is insulated on site.

Benefits:

Handling of large flowrates

Optimised configuration for proper flow distribution

Flanged terminations for time effective installation at site

Coldboxes

A coldbox covers several exchangers, vessels, piping, instrumentation and valves installed in a carbon steel compartment.

Benefits:

Cost-effective solution

Perlite filling (insulation)

Supplied as a turnkey packaged unit

Time effective installation at site

Block-in-shell

A block-in-shell comprises one or more heat exchanger blocks installed in a shell instead of a tube bundle. This is a highly efficient and cost-effective alternative to standard shell-and-tube heat exchangers.
